Listen to the NBC Symphony Orchestra 60 minutes performance (photos), Beethoven's Symphony No. 7 extracts here (1936), along with extracts from la Traviata (1946). As for me, I own the precious Maestro Furioso Box Set (10 CDs) that gives an exhaustive view on Toscanini.

YouTube extracts: Chorus of the Hebrew Slaves, Nabucco, conducted by Toscanini (sound only, the photos shown of Milan just after WWII and especially the devasted Scala are very impressive though + there’s a short video of Tosacanini at the end of the recording), May 11, 1946, Concerto della Ricostruzione, Scala. Verdi’s Hymn of the Nations, NBC Symphony Orchestra, 1943, with tenor Jan Peerce.Bruno Walter, Arturo Toscanini, Erich Kleiber, Otto Klemperer and Wilhelm Furtwängler.
